Abstract:
We present the first results from an optical reverberation mapping
campaign executed in 2014 targeting the active galactic nuclei (AGNs)
MCG+08-11-011, NGC 2617, NGC 4051, 3C 382, and Mrk 374. Our targets
have diverse and interesting observational properties, including a
"changing look" AGN and a broad-line radio galaxy. Based on
continuum-Hβ lags, we measure black hole masses for all five
targets. We also obtain Hγ and HeIIλ4686 lags for all
objects except 3C 382. The HeIIλ4686 lags indicate radial
stratification of the BLR, and the masses derived from different
emission lines are in general agreement. The relative responsivities
of these lines are also in qualitative agreement with photoionization
models. These spectra have extremely high signal-to-noise ratios
(100-300 per pixel) and there are excellent prospects for obtaining
velocity-resolved reverberation signatures.
Description:
We obtained spectra on an approximately daily cadence between 2014
January 04 and July 06 UTC using the Boller and Chivens CCD
Spectrograph on the 1.3m McGraw-Hill telescope at the MDM Observatory.
We also obtained six epochs of observations with the 2.3m telescope
at Wyoming Infrared Observatory (WIRO) and the WIRO Long Slit
Spectrograph.
Our spectroscopic observations are supplemented with broadband imaging
observations. Contributing telescopes were the 0.7m at the Crimean
Astrophysical Observatory (CrAO), the 0.5m Centurian 18 at Wise
Observatory (WC18), and the 0.9m at West Mountain Observatory (WMO).
In addition, we obtained ugriz imaging with the LCO 1m network, which
consists of nine identical 1m telescopes at four observatories spread
around the globe. These data were originally acquired as part of LCO's
AGN Key project (Valenti+ 2015ApJ...813L..36V 2015ApJ...813L..36V).

Note (1): The luminosity distance DL in a concensus cosmology, except for
NGC 4051 for which the luminosity distance is
from Tully+ (2008, J/ApJ/676/184).
Note (2): The number of nights with clear and stable conditions on which each
object was observed. Each object had three observations per night,
which were used to calculate the narrow [OIII]λ5007 line flux.
Note (3): The fractional variation of the [OIII]λ5007 line light curve,
which serves as an estimate of the night-to-night calibration error
(Section 2.5.1).
Note (4): The observed luminosity (corrected for Galactic extinction),
calculated from the observed 5100Å rest-frame light curve and
Column "Dist".
Note (5): The luminosity of the host-galaxy starlight in the spectroscopic
extraction aperture, also corrected for Galactic extinction
(Section 5.1). Note that Column "logL5100" includes the contribution
from the host galaxy.
